您有HTC手机并希望更改手机上的分区吗？安全功能是否妨碍您这样做？本文将讨论HTC S-OFF，它可以让您关闭此安全协议。作为此过程的一部分，您将需要了解文章中介绍的HTC引导加载程序。完整阅读这篇文章，以更好地了解这个主题。
HTC S-OFF 是什么？(What is HTC S-OFF?)
通常，所有设备都具有S-ON安全协议，在向公众发货时，它会在Radio分区上放置一个标志。也就是说，HTC手机的安全标志是默认开启的。您可以在HTC(HTC)手机上关闭此标志。这是如何做到的：
- 它存储在设备的无线电中，关闭它可以让您写入系统内存。
- 它会阻止您在HTC安卓手机上使用任何自定义ROM(ROMs)、启动图像、恢复等。
- 它还阻止您访问NAND闪存并限制您对设备上的NAND分区进行永久性更改。
- NAND分区包括Boot分区、recovery分区、Radio、System分区等。
- 只需重新启动手机，即可将您在S-ON的(S-ON)HTC手机上所做的更改恢复为正常状态。
- S-OFF 无法让您在重新启动时灵活地恢复手机的功能。您可以从通知顶部的文本中了解手机是 S-ON 还是 S-OFF，或者标志是打开还是关闭。
注意：(Note:)关闭安全或 S-OFF 是用户的全部责任，在需要之前不得这样做。
您可以在 HTC 手机上使用 S-OFF 获得 Root 权限吗？(Can You Have a Root Using S-OFF on HTC Phone?)
root 类似于在您的Linux 操作系统(Linux OS)中拥有另一个用户。在引导加载程序上打开HTC手机上的(HTC)S-OFF允许您刷新包文件，例如Superuser.apk和 su 二进制文件。这里要注意的要点是在刷入超级用户(Superuser)之前刷入恢复。重新启动手机后，您可以在手机上获得root权限。因此(Hence)，HRC S-OFF不会在您的手机上创建任何根目录，但允许您刷写您可以拥有的程序。

-
无需对固件映像进行签名检查(No need for the signature checks for firmware images)- 所有固件 zip 都必须由HTC进行数字签名才能通过引导加载程序进行刷新。在HTC(HTC)安卓手机上关闭 S-OFF可让您绕过上传自定义固件映像、未签名启动、启动和HBOOT映像以及恢复所需的安全检查。S-OFF 标志将允许您刷新包含分区的单独映像的未签名固件 zip。换句话说，它使您能够最大限度地定制您的Android手机。
使用 HTCdev 解锁引导加载程序(Use HTCdev to Unlock Bootloader)

What is HTC S-OFF?
Do yоu havе an HTC phone and wish to alter partitions on your phone? Is the secυrity feature disturbing you from doing thiѕ? This article will deal with HTC S-OFF, which lets you turn off this security protocol. Aѕ a part of this procеss, you will be required to learn about the HTC bootloader, which is covered in the article. Read the artісlе completely to have a better insight оn this topic.
What is HTC S-OFF?
Generally, all the devices have the S-ON security protocol, for which it places a flag on the Radio partition while being shipped to the public. In other words, the security flag of the HTC phone is turned on by default. You can turn off this flag on your HTC phone. Here’s how to do it:
- It is stored on the device’s radio and turning it off can allow you to write to the system memory.
- It hinders you from using any custom ROMs, splash images, recovery, etc., on your HTC android phone.
- It also prevents you from accessing the NAND flash memory and restricts you from making permanent changes to the NAND partitions on the device.
- The NAND partition includes the Boot partition, the recovery partition, the Radio, the System partition, etc.
- The changes you make on the HTC phone with the S-ON can be reversed to normal by simply rebooting the phone.
- S-OFF doesn’t give you the flexibility to revert to the functions of your phone upon a reboot. You can know if the phone is S-ON or S-OFF or if the flag is on or off, from the text on the top of the notification.
Note: Turning off the security or S-OFF is the complete responsibility of the user and must not be done until there is a need for it.
Can You Have a Root Using S-OFF on HTC Phone?
A root is similar to having another user in your Linux OS. Turning the S-OFF on your HTC phone on the bootloader allows you to flash a package file such as Superuser.apk and the su binary. The main point to note here is to flash a recovery before flashing a Superuser. When the phone is rebooted, you can have a root on your phone. Hence, the HRC S-OFF doesn’t create any root on your phone but allows you to flash programs by which you can have one.

Benefits of Turning S-OFF
The benefits of turning S-OFF on HTC are listed below.
-
Access and overwrite the partition drives on the HTC phone– By turning the S-OFF on your HTC phone, you can access the NAND portion of the device. This means that you will get access to unlock the partitions on the device and you can alter them. The partition dives on the phone cannot be altered by default. By turning the S-OFF flag, you can overwrite the code on the partition drives while the OS of the device is booted.
-
No need for the signature checks for firmware images– All the firmware zips must be digitally signed by the HTC to be flashed through the bootloader. Turning S-OFF on your HTC android phone allows you to bypass the security check required for uploading custom firmware images, unsigned boot, splash and HBOOT images, and recovery. The S-OFF flag would allow you to flash unsigned firmware zips that contain separate images of the partitions. In other words, it enables you to have the maximum customization of your Android phone.
Use HTCdev to Unlock Bootloader
HTCdev doesn’t set the bootloader to S-OFF but it unlocks the partitions on your phone. This would allow you to flash a custom recovery and then flash a custom ROM on your phone, for which you are not needed to keep HTC S-OFF. Below is the listed information:
- You need to register on the website and by logging in, you can unlock the bootloader on your HTC phone.
- This method is officially released by the HTC and it gives you limited unlocking to the partitions like the boot, system, and recovery, on your phone.
- The restricted unlocking method is necessary for security reasons and it prevents you from flashing any random firmware zip to your partitions. This, however, doesn’t let you unlock your SIM card.
- The unlocking changes the software of your phone and may give rise to some unexpected problems. This might change the values of Hearing Aid Compatibility (HAC) or Specific Absorption Rate (SAR) or may result in overheating of the phone.
- In addition to these, some of the content you might have purchased through third-party vendors or HTC may be invalidated or be inaccessible due to DRM security keys.
- You may not be able to use the update of the phone through Firmware over the Air or FOTA. If there are some irreversible changes made on your phone, it might not come under the warranty provided to you by the HTC.
